GATE-SPRING.

Speceaton of Letters Patent.

Patented June 9, 1914.

Application filed February 12, 1914. Serial No. 818,255.

T0 all whom t may concern o Be it known that I, EDWIN CROWLEY, a citizenof the United States, residing at Minneapohs, in the county of Hennepinand State of Minnesota, have invented certain new and usefulImprovements in Grate- Springs; and l do hereby declare the -t'ollowingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

My invention has for its object to provide an extremely simple andhighly eflieient spring for doubleswinging gates, especially designedfor use with my gate latch, disclosed and claimed in my coi-pendingapplication, tiled February 10, 1913, under Serial Number 747,393.

To the above end, generally stated, the in vention consists oi the noveldevi es and combinations of devices hereinafter described and defined inthe claims.

In the accompanying dra-wings, which illustrate the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawings: Figure 1 is a vi-ew in elevation, showing theimproved spring applied to a gate and a gate-post; and Fig. 2 is adetail view on an enlarged scale, with some parts sectioned on the linem2 032 of Fig. 1.

yllhe gate shown comprises a rectangular marginal trame 1 and a wovenwire panel 2 secured to said frame. This gate is secured to a gate-post3 by a pair of hinges 1, for double-swinging action. For holding thegate closed, a latch, preferably ot the construction shown in my aboveidentified application, may be used, but, for the purpose ot' this case,it is not thought necessary to illustrate the same.

Upper, lower and intermediate brackets 5, 6 and 7, respectively, arevertically spaced, one above the other, between the hinges l, andrigidly secured to the post 3. Rotatively mounted in the brackets 5 and6 is a pair of inwardly projecting headed studs 8, secured in differentpositions, with respect to the brackets 5 and G, by pins 9 passedthrough radial perforations in the heads of the studs 8. Rigidly securedto the inwardly projecting studs 8 is a pair of reversely acting axiallyalined coiled springs 10i. The inner ends et these springs 10 areloosely telescoped onto a pair of reversely project ing studs 11integrally formed on the upper and lower faces of the bracket '7. Theinner ends of the springs 10 terminate in lateral extensions 12, whichengage opposite vertical edges oi a pair of stops 13, and hold saidsprings under tension. These stops 13 are integrally formed with thebracket 7, and extend parallel with the studs 11. Obviously, byadjusting the studs 8 in the brackets 5 and 6, the springs 10 may beplaced under any desired tension. Outward of the stops 13, the springextensions 12 engage opposite sides of the vertical member ot the gateto which the hinges 1- are secured, as best shown in Fig. 2. Thesespring end extensions 12 normally hold the gate centered.

1When the gate is opened in the direction of the arrow marked on Fig. 2,the spring end extension 12, on the side of the gate which is swungoutward, is moved away from its stop 13, and becomes operative to returnthe gate to its normal or centered position. During this movement of thegate, the other ot' said springs is held in a normal position by theengaged stop 13, but becomes operative at the return movement of thegate, to again center the same. Then the gate is swung in a reversedirection from that just described, the action ot said springs will alsobe reversed.

The above described device, while eX- tremely simple, and of small costto manufacture has, in actual usage, proven highly etlicient `for thepurpose had in view.

1. The combination with a. gate, and a gate-post to which said gate ishinged, for double-swinging action, of upper, lower and intermediateanchor brackets secured to said gate-post, and a pair of reverselyacting coiled springs anchored, at their outer ends, to said upper andlower brackets, and loosely seated, at their inner ends, on saidintermediate bracket, and having laterally projecting ends engagingopposite sides of said intermediate bracket and opposite sides of saidgate.

2. The combination with a gate, and a gate-post to which said gate ishinged, for double-swinging act-ion, of upper, lower and intermediateanchor brackets secured to said gate-post, said intermediate brackethaving oppositely projecting studs and stop lugs, a pair oit reverselyacting coiled springs ad justably secured, at their outer ends, to saidupper and lower braokets, and with their In'testiinony whereof I afiixmy signature coiled inner end port-ions loosely surroundin presence oftWo Witnesses.
